LAST.

Appneation filed Aprn 27, 1925. serial No. 26,034.

y citizen of the United States, residing at Portsmouth, in the countyV ot Scioto,- and State otOhio, rhave invented certain new and usetullmprovements in Lasts, of which theV following is a specication, reference being had therein to the accompanying drawing.

My invention relates to lasts. Y

It is the object of my invention to provide a last which will be yieldingly heldin its expanding or collapsed position.

It is-a further object of my invention to Y Jrovide a last havin@r `a resilient lever and b link :tor the dual purpose of connecting the parts so that a line drawn between the centers of the ends of the link will pass over the deadcenter of movement of the last parts and through the leverage. of the link of the spring lever; leX the spring. g

It is my object to'Y provide a link` which is anchored to alast part at one end and to Ythe spring lever at the otherso arranged thatV the pivotal mounting of the link and the pivotal mounting'l of the lever on the last parts will not have the line drawn between their centers pass over the center of'movement of the last parts.

It is a further object to have'the pivotal point of Vsupport of the link so arranged that a line drawn betweenfthecenters there, of will pass over the centerof movement of the last parts, one end of the link being mounted upon the spring lever.k A f s Referring to the drawings: Figure l is a side elevation partially in section of a last'with the link and spring lever construction of my invention;

Figure 2 is a plan view ofthe link and:

spring construction `with the anchorv pins partially broken away.

' is designated 3. The surface is'fla-t save for theyexception of a transverse semicirc ilar f groove 4f' for receiving` a transverse cyl1n.

Referring tothe drawings in detail, 1 is the toe part of a last having a cut away or slottedy portion 2 for receiving the spring and links. The rear face of this last half drical shoulder 5 of the heel part This heel part is provided: with a cut away slot'7.

An abutment pin 8 is provided'inthis pro! jecting shoulder 5, the center of the pin. 8V

being located on the center of movement of the last parts. The forward face 9 ot the vof the last collapsing. f

In the rear lastv half near the bottom thereof and transversing the slotk7 is an anchor' pin 10. Mounted on this anchor pin are arched shaped links 11. The other end offthese links is pivoted on a stud 12 which is carried by the'sp'ring lever which consists of a lever portion 18 pivotedv lon an anchor pin 14;' at one end and to the links 11 ati.

to the. spring lever to a point where it pro-,

ljects through the front last half into the rear last halt, this part beingmarked 15. Viiie rear end otthis party 15 passes downwardly at 16 and then forwardly at 17 vparallel toa space overthe part 15 and then' terminates in a hook 18 which is hooked over the abutment pin' 8. l

It will be observed, therefore, `that a line center ot the pin 8 and that a line drawn between centers of the pin 10` and 12 willpassover the center of the pin 8.

. It will be understood that I desire to com yprehend within my invention such modifi-k cations as may be necessary to adapt it to varying conditions ot use.

Having thusl fully describedby invention, what I claim as new and desire to secure by Letters Patent, is f 1. In aV last7 a toe part anda heelv part adapted to move one on the other, a link joining said parts, a spring lever piv'oted on one ot said parts and engaging .the other of said parts, one end otsaidV link beingpivoted` onV said spring lever andy the other pivoted on another last part than that associated with its point of, pivotal connection with the springlever, and an abutment pincarried by one of said last parts against which the end of the spring lever engages.

connecting said parts, a spring lever pivoted on one ofl said parts, said link being pivoted thereto at a point remote ytroni the pivotal mountingof the spring lever, and an ahnte ment pincarried by one ot said last parts againstv'which vthe end of thevspring lever engages. y
